IMPROVEMENT IN WASHING-MACHINES.

The schedule referred to ln these Letten Patentand making parl: of the uma.

To all whom it may concern Be it known that I, Enwnv KNocK, of Vermont, in the county of Fulton and State of '.Illinois, have invented a new and useful Improvementin Washing- Machines; and I do hereby declare that the following v is a full, clear, und exact description thereof, which will enable others skilled in' the art to make and use the same, reference beinghad to the accompanying drawing forming part of this specification, iu which- Figure l is a top view of my improved machine part ofthe rubber being broken away to show'the construct-ion.

Figure 2 is a vertical longitudinal section of the same taken through the line x x, fig. 1.

Similar letters of reference indicate correspondingv parts.

My invention has for its object to furnish'a'n improved washing-machine, simple in construction, efective in operation, and convenient in use;` and It consists in the construction and combination of various parts of the machine, as hereinafter more fully described.-

y A is the outer box or 'tub of the machine, which ,is made semi-cylindrical in form, aud is supported upon legs B of such 'a length as to raise the machine to a convenient height.

C is the receiver, into which the clothes are placed to be washed.

The receiver C is also made semi-cylindrical in form, and of such a size as to iit loosely into and work freely in the interior of the box A.

The receiver O is pivoted to the sidesofthe box A, so that it may be rocked upon said pivots.

The bottom of the receiver C is made double, the' inner plate or bottom cl being corrugated transversely, as shown in figs. l and 2, so as to have about the form of a hand-rubbing board, the -outer plate or bottom oz being made smooth to encounter less resis ance in passing through the water. 1

The lower or middle parts of the two bottoms cl cz have numerous holes formed through them, to allow y the water to pass in and out-freely. ,I

A number of larger holes are also formed through the-lower parts of the sides of the receiver O, to facilitate -the circulation of the water. D is the rubber, which is also made semi-cyliln drical in form, and of such a size as to tit-loosely into and work freely in the interiorof the receiver U.

The convex side of the rubber D is formed by at-v taching parallel strips al' to the curved edges of 'the sides of lsaid rubber.

The strips d' are so arranged as to leave narrow spaces between Athemfor the free passag'e of the water, and theiroutersides are-rounded off so as to prevent the said strips from lpresenting any sharp corners to out the clothes. v

To the' upper parts of the sides of the rubber D are attached journals E, which work between standards F, or in slotted standards attached tothe box` ends of the standards H attached to the sides of the box A at one end of the machine.

Tov one end of `the shaft G is attached; a crank, I, .by means of A,which the machine is operated.

Upon the middle part of the shaft G are formedv two cranks, gI g2, projecting in opposite directions from the line of the said shaft. f

`To one of these cranks, as g, is pivoted the .upper end of the vconnecting-rod AJ, the Vlower end of which is pivoted to the end ofthe receiver G, so that the said receiver may be rocked upon its pivots by thevre'v'olution 0f the shaft G. Q

To the other clank, as g2, ispivoted lone endof the connecting-rod K, the other eudof which is-pivoted to the standard L attached to the rubber D, so that the said rubber maybe rocked upon its journals by revolving the shaft G. f By this construction the receiver() and rubber D will move iu opposite directions, and will thus pro-l duce a much-greater elect upon the clothes v'placed between the said parts.

The rod K is adj nstably pivoted tothe standard L, so that by moving it up or down upon said standard the throw or amount of movement of the rubber D may be regulated at will.

In using the machine, the clothes are placed in the receiver Gand the rubber D is placed upon them,.and

by operating the crank I the clothes lwill -be rubbed between the two moving surfaces, cleaning them perfectly in a .very short time. l

. Having thus described mynvention,D i .v I claim as new and desire to secure by Letters Patent- An improved washingmachine,formed by the combination of thesemi-cylindrical box A, semi-cylindric al' movable receiver 0 cl c2, semi-cylindrical rubber D d', standard L, connectingfrod K, crank-shaft G g g,

connecting-rod J,and crank I, with each other, saidt parts being' constructed and'operating substantially as herein shownaud described, and for the purpose set forth.
